rockbox/apps/plugins/lib/gray_scroll.c, branch master My Rockbox tree The old grayscale library is now officially dead. 2008-01-13T00:21:45+00:00 Jens Arnold amiconn@rockbox.org 2008-01-13T00:21:45+00:00 c6b5d5531b1e1ea53ee860e939dc9eb638c415a9 git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16067 a1c6a512-1295-4272-9138-f99709370657

Grayscale lib: Using a 32x32->32 bit multiplication is better on ARM, as 16x16->32 bit isn't a single instruction. Renamed the macro for pointing out that it's not necessarily 16 bit anymore, and to avoid collisions with similar macros in plugins. 2006-11-05T14:40:14+00:00 Jens Arnold amiconn@rockbox.org 2006-11-05T14:40:14+00:00 32c69452d699ce4dbf35e843b2f69507321e1b71 git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11436 a1c6a512-1295-4272-9138-f99709370657

* Assembler optimised gray_update_rect() and writearray() for arm (greyscale iPods). * Some slight optimisations for coldfire (H1x0) and SH1 (archos). * Comment and formatting cleanup. 2006-08-07T17:21:38+00:00 Jens Arnold amiconn@rockbox.org 2006-08-07T17:21:38+00:00 c00d799fa3a568ecb8649b5ce6d40366707b9551 git-svn-id: svn://svn.rockbox.org/rockbox/trunk@10473 a1c6a512-1295-4272-9138-f99709370657

Grayscale library ported to the grayscale iPods, first version. Added C reference versions of gray_update_rect() for both horizontal and vertical pixel packing. gray_update_rect() and gray_ub_gray_bitmap_part() not yet assembler optimised. Grayscale screendump doesn't work yet. * Fixed button assignments for iPod in grayscale.c 2006-08-07T01:46:42+00:00 Jens Arnold amiconn@rockbox.org 2006-08-07T01:46:42+00:00 c214e7bb0c3e97d22ecedb1c62f193e19a1d4818 git-svn-id: svn://svn.rockbox.org/rockbox/trunk@10468 a1c6a512-1295-4272-9138-f99709370657

Finally - grayscale library support for the simulators. Currently SDL only, win32 and x11 won't link anymore due to missing simulator functions. 2006-02-26T13:37:42+00:00 Jens Arnold amiconn@rockbox.org 2006-02-26T13:37:42+00:00 6a972e02497d3015236189f72931c3d59fa51755 git-svn-id: svn://svn.rockbox.org/rockbox/trunk@8845 a1c6a512-1295-4272-9138-f99709370657

Added memmove() to codec API & plugin API, and changed codeclib and plugin libs to use it. 2006-02-06T16:04:01+00:00 Jens Arnold amiconn@rockbox.org 2006-02-06T16:04:01+00:00 e6e8aa95197040d5f9e7125819a0a7f047a83f24 git-svn-id: svn://svn.rockbox.org/rockbox/trunk@8602 a1c6a512-1295-4272-9138-f99709370657

H1x0: Changed lcd_blit() and the grayscale library to use the same internal format as on archos (1bpp). While the slowdown of the ISR is minimal (the intermediate buffers are in IRAM), the planar grayscale buffer takes only half the space for a given depth, and gray_update[_rect]() and unbuffered drawing/scrolling are faster because less data needs to be moved. It should also make porting of video.rock somewhat easier. * Archos recorders, Ondios: Some slight optimisations of the grayscale library. 2005-09-30T20:10:27+00:00 Jens Arnold amiconn@rockbox.org 2005-09-30T20:10:27+00:00 1a40e109333b8206140594fce746f7972a4d0d86 git-svn-id: svn://svn.rockbox.org/rockbox/trunk@7571 a1c6a512-1295-4272-9138-f99709370657

Grayscale lib: Moved the shift count doubling for unbuffered up/down scrolling out of the asm block itself (cosmetic). 2005-07-28T14:08:58+00:00 Jens Arnold amiconn@rockbox.org 2005-07-28T14:08:58+00:00 feaf62704ed3a3b2eb98f0e49afc1559e0655ba9 git-svn-id: svn://svn.rockbox.org/rockbox/trunk@7250 a1c6a512-1295-4272-9138-f99709370657
